Centre Social icons in footer

Hi,

I have added social icons and text to the footer in a child theme. The text still displays in the centre but the icons align left, I’d like them to also align centrally. I have tried adding margins auto and align centre to the container div but had no luck with that. Appreciate any guidance.

<div <?php echo mesmerize_footer_container(‘footer-simple’) ?>>
<div <?php echo mesmerize_footer_background(‘footer-content center-xs’) ?>>
<div class=”gridContainer”>
<div class=”row middle-xs footer-content-row”>
<div class=”footer-content-col col-xs-12″>
<?php echo DISPLAY_ULTIMATE_PLUS(); ?> ? 2018 KW Web Solutions
</div>
</div>
</div>
</div>
</div>

Thanks
